Hydraulic is as subtle as a brick in the face, which is basically the way he orders the Monster Truck Patrol to attack the Decepticons . . . smash into them headfirst in a painful area. Hydraulic's simple, straightforward nature might give some the impression he's not very bright, but he's actually a remarkably intelligent being. He just knows what works for him and his team, and that's brute force.
